Monthly Gardening Tips - September 2021
IN THE GARDEN
As the days shorten many plants begin to fade, and flop. Less watering is required. Remove seed heads where you want to prevent next generation seedlings from establishing. Keep weeding!
Here are a few photos of flowering plants worth investing in (as seen in the Richmond area! in late August):
Perovskia atriplicifolia, Russian Sage. Prune after flowering
Erigeron karvinskianus. Hard prune in February/March
Trumpet lily. Remove seed heads after flowering.
Passion flower. Tidy in autumn. Prune in March.
'Before and after' summer prune of Wisteria. Spur back in Jan/Feb
Bizzie Lizzie in pots
Bowl planted with 6 surfina Petunas and 4 Helichrysum petiolare
Mixed Nasturtiums fronting a window box. Easily grown from seed
Tuberous begonias in a hanging basket. Not hardy
Globe artichoke. Cut old stems to ground level Aug/Sept.
Ceratostigma plumbaginoides. Cut almost to ground level in Feb/March
